Arnold, CA…The forecast for the West Slope Northern Sierra Nevada is as follows. We also start the week with heat warnings. For those of you new to The Pine Tree we post our weather by elevation starting at Lake Alpine – Bear Valley levels and dropping down by community. These numbers also work well for the Hwy 88 and the Hwy 108 corridors. As the crow flies Hwy 88 and Hwy 109 are only 15-18 miles north and south respectively. So the temps by elevation are usually accurate within a degree or two regardless of which pass you are on.
